Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a wristwatch type GPS.
The data storage capacity is relatively small, such as a portable GPS receiver and a vehicle-mounted navigation device that can be carried by the user and have a relatively small data storage capacity. The present invention relates to a large navigation device and a navigation system including these devices.

[0002]

2. Description of the Related Art As a conventional portable GPS receiving device, for example, a small portable GPS receiving device such as a wristwatch-type GPS receiving device worn on an arm is known. In such a portable GPS receiver, a portable GPS
Due to limitations on the size of the receiving device, a large-capacity recording medium drive such as a CD-ROM drive or a DVD drive cannot be mounted, and the memory has a small capacity, so that a wide range of map information and the like can be stored. Can not. In addition, portable GP
It is difficult to improve the operability due to limitations on the size of the S receiving device and the like, and it is difficult to directly operate the portable GPS receiving device to set a destination and the like.

Therefore, in general, when using a portable GPS receiver, before going out of the house, the user sends map information, destination information, and other navigation information around the place to be used to a personal computer at home. P
C) or the like is input in advance. For example, if you go to the mountains by car to picnic or hike, or go to a town you do not know by car, before leaving your home, you can use your PC or other device at home to provide navigation information around the place you are going to. Input to the GPS receiver, move to the place by car, get off the car with the portable GPS receiver, and walk around the place.

[0004]

However, according to the above prior art, before departure in a vehicle such as an automobile,
PC at home to provide navigation information around the place to go
Must be input to the portable GPS receiver from
If the place to go is changed because the parking lot is full or there is an accident, if the place to go is not decided in advance, if you forget to enter navigation information, etc. Surrounding navigation information is portable G
There is a problem that the portable GPS receiver cannot be used effectively because it is not input to the PS receiver.

[0005] The present invention has been made in view of the above, and even when navigation information around a place actually visited by a vehicle is not input to the portable GPS receiving apparatus in advance, the portable GPS receiving apparatus can be used.
